I think it describes it quite well as long as you assume the problem of making a 3D model from a picture is already a solved but computationally expensive problem. That's the part it doesn't go into but that's not what this research is about. Though I think most readers will still be interested in that - I didn't know it had been solved already.

It's not making a surface mesh, it's putting voxels on the surface. Again, it doesn't make that distinction very clear up front so I guess it's not targeted at people familiar with traditional 3D surface meshing.
